News Articles Featuring John Hayes

You’ll never be a great cook if you don’t have the nafas

Why is food produced by some cooks (usually grandmothers) so much better than the exact same food—down to the recipe—produced by others? It could be lack of skill, or impatience, or bad ingredients or equipment. But it could also be lack of nafas.

Do You Have Nafas, the Elusive Gift That Makes Food Taste Better?

The Arabic word refers to a mysterious factor that renders some people’s cooking exceptional. Whether it’s innate or acquired is up for debate.

Can’t Take the Heat? A Taste for Spicy Foods Can Be Learned.

If you feel left out, here are tips for enjoying (or at least tolerating) the burn.

Baby food product names may not accurately reflect ingredient amounts

The descriptions on the fronts of infant and toddler food packages may not accurately reflect the actual ingredient amounts, according to new research. The team found that vegetables in the U.S. Department of Agriculture’s “dark green” category were very likely to appear in the product name, but their average order in the ingredient list was close to fourth.


This NOVA episode features John Hayes, associate professor of food science and director of the Sensory Evaluation Center. It aired on PBS member stations across the country.

COVID’s toll on smell and taste: what scientists do and don’t know

Researchers are studying the sensory impact of the coronavirus, how long it lasts and what can be done to treat it.

UF neuroscientists study scratch-and-sniff tests to detect COVID-19

The National Institutes of Health awarded $912,000 in a CARES Act grant to UF researchers, in collaboration with Pennsylvania State University and Arizona State University, to conduct a two-year study using two smell tests that can detect COVID-19 cases.

Researchers investigate an at-home 'scratch-and-sniff' test for COVID-19

A self-administered "scratch-and-sniff" test for COVID-19 may be around the corner, according to researchers at Penn State, the University of Florida, and Arizona State University.

Daily DIY sniff checks could catch many cases of COVID-19

Smell loss – called anosmia – is a common symptom of COVID-19. For the past nine months, the two of us – a sensory scientist and an infectious disease epidemiologist – have applied our respective expertise to develop smell-based screening and testing programs as part of a response to the SARS-CoV-2 pandemic.

Is a sweet tooth actually a thing?

My youngest sister is a dessert fiend. At least once a week, she texts or posts a photo of a concha, cupcake, or other confection she bought to #treatherself. While I may share around half my genes with her, I don’t share her abiding love of sugar. (Salt is my vice — if you place a cheese platter in front of me, I will demolish it.) As we continue to hole up and eat our feelings during the pandemic, I wonder why my sister and so many others self-soothe with sweets, while the rest of us seek solace in other foods. Is a “sweet tooth” just a figure of speech, or does it have a biological basis? Is a sweet tooth actually a thing?
